"SVC Assist" is a facility that performed some common housekeeping operations on behalf of the SVC - for example, copying the information stored at the last SVC interruption into the current request block, saving general registers, and loading the general registers with appropriate values.
It was implemented by opcode x'E503'. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Dori Polotsky Sent: Wednesday, April 4, 2018 10:18 AM To: [email protected] Subject: Explanation about the SVCASF bit ("SVC can be assisted") in the SVC table? Hello, Does anyone know the meaning of the SVCASF bit (x'01') of the SVCTP byte of the SVC table? If I am not mistaken, on our system (z/OS 2.2 ADCD) following the IPL this bit is off for all SVC's except SVC 13 (ABEND, IEAVTRT2) and SVC 26 (LOCATE / CATALOG, IGG026DU). Also, I did not see an option to select the value for this bit with SVCUPDTE. Any insights would be appreciated. Thank you very much, Dori ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ================================ Rocket Software, Inc. and subsidiaries ■ 77 Fourth Avenue, Waltham MA 02451 ■ Main Office Toll Free Number: +1 855.577.4323 Contact Customer Support: https://my.rocketsoftware.com/RocketCommunity/RCEmailSupport Unsubscribe from Marketing Messages/Manage Your Subscription Preferences - http://www.rocketsoftware.com/manage-your-email-preferences Privacy Policy - http://www.rocketsoftware.com/company/legal/privacy-policy ================================ This communication and any attachments may contain confidential information of Rocket Software, Inc.
